- A Jet Airplane In Level Flight Has A Mass Of 8 60 10 Kg And The Two Wings Have An Estimated Total Area Of 91 0 M E W 1 (10.49 KiB) Viewed 31 times
(a) What is the pressure difference between the lower and upper surfaces of the wings?
Pa
(b) If the speed of air under the wings is 229 m/s, what is the speed of the air over the wings? Assume air has a density of 1.29 kg/m3.
m/s
(c) Explain why all aircraft have a "ceiling," a maximum operational altitude.
The density of air
